Public hospitals have formed a relatively perfect working foundation in the introduction and training of young talents,but the evaluation system of young talents is not perfect.Based on the requirements of high-quality development,grasp the principle of party management of talents,combine the talents development situation in Jiading District Maternal and Child Health Care Hospital,takes the special training of young talents in administration as the starting point,comprehensively uses the literature method,interview method and Delphi method to establish the index database,uses the exploratory factor analysis meth-od to calculate the index weight,and constructs the evaluation model of young talents in hospital administrative management,so as to help hospitals better screen and evaluate talents and give full play to the value and role of talents as the first resource.

Young management talents are the driving force behind the refined management of hospitals and the future and hope of high-quality development.In the context of the new era,high-quality development has become the main theme of reform and development in public hospitals,which puts forward new and higher requirements for the cultivation of young management tal-ents in hospitals.Based on literature research,this article systematically summarizes and explores the concept and characteristics of young management talents in hospitals.Taking Jiangsu Provincial People's Hospital as an example,it actively supports and serves the growth and development of young management talents through specific practices such as optimizing organizational man-agement,improving training systems,strengthening incentive mechanisms,and smoothing development channels.These practices have achieved good results and aim to provide references for the cultivation and development of young management talents in pub-lic hospitals in China.

Triple-negative breast cancer(TNBC)is a highly aggressive and prognostically unfavorable subtype.Tertiary lymphoid structure(TLS)within the tumor microenvironment,comprising dendritic cells,B cells,T cells,and other immune cells,modulate the tumor immune response.The heterogeneity of TLS in TNBC,such as density,structural maturity,and molecular expression patterns,affects the tumor immune microenvironment and,consequently,treatment responses and clinical outcomes.Studies indicate a positive correlation between the density and maturity of TLS and the pathological complete response(pCR)of TNBC patients,with TLS enhancing the quantity of tumor-infiltrating immune cells and improving anti-tumor immune responses,thereby increasing sensitivity to chemotherapy and immunotherapy.Recent research has found that mature TLS are associated with effective immune responses,becoming significant predictors of treatment response.The combination of TLS with immune checkpoint inhibitors has shown promising prospects.Research demonstrates that promoting the formation or enhancing the functionality of TLS can improve anti-tumor immune effects and enhance treatment outcomes for TNBC patients.Targeting TLS may reduce immune evasion and increase the sensitivity to immunotherapy.However,clinical application of TLS still faces challenges,particularly the impact of their heterogeneity on treatment response.Current assessment methods for TLS are not standardized,lacking a uniform standard and diagnostic system,which limits their widespread application.Future research should focus on resolving these issues by developing standardized assessment tools and further exploring the role of TLS in immune escape and resistance mechanisms.This review aimed to summarize and analyze the existing research progress on TLS in TNBC,in order to provide new ideas for the development of personalized immunotherapy strategies.

AIM:To construct and breed infertility model mice with ATP/GTP binding carboxypeptidase 1(Agtpbp1)gene knockout homozygote(Agtpbp1-/-)by CRISPR/Cas9 technology,so as to provide an animal model for the subsequent exploration of the pathogenesis of Agtpbp1 gene in male sterility.METHODS:The CRISPR/Cas9 technology was used to obtain Agtpbp1 gene knockout heterozygote(Agtpbp1+/-)mice according to the data of the main protein functional region of Agtpbp1 gene and combined with Cas9 nuclease.The obtained Agtpbp1+/-mice were mated,and their offspring were genotyped by PCR and agarose gel electrophoresis.The expression of Agtpbp1 at different levels was detected by RT-PCR,Western blot and immunohistochemical staining to support the identification results.The HE staining was used to observe the mouse cerebellum and eyeball structure to analyze the effect of Agtpbp1 gene knockout on Purkinje cells and photoreceptor cells.The symptoms of ataxia in mice were observed in combination with behavioral tests.The growth of mice was observed,and the changes of testicular tissue volume and weight of male mice were analyzed.The HE staining was used to observe the changes of testicular structure,and PAS staining was used to observe the changes of testicular germ cell cycle.Finally,sperm analyzer was used to analyze the sperm motility,so as to analyze the growth and develop-ment of the mice.RESULTS:The male and female Agtpbp1+/-mice could continue to mate,and three genotypes,Agtpbp1 wild-type(Agtpbp1+/+),Agtpbp1+/-and Agtpbp1-/-,were obtained.The genotypes of the offspring mice were successfully identified by PCR.The results of RT-PCR,Western blot and immunohistochemical staining verified the successful con-struction of Agtpbp1-/-mouse model at different levels(P<0.05).The results of HE staining showed that Purkinje cells were lost in the cerebellum of Agtpbp1-/-mice and the number of photoreceptor cells in the eyeball was reduced.Behavioral tests confirmed that Agtpbp1-/-mice had ataxia symptoms such as motor dysfunction and uncoordinated movements.Com-pared with control group,the testicular volume and weight of Agtpbp1-/-mice were significantly reduced.The results of HE staining showed a very small amount of sperm in the testis of Agtpbp1-/-mice.Combined with the sperm analyzer,it was ob-served that the sperm motility,vitality and movement rate of Agtpbp1-/-mice were significantly lower than those of the con-trol mice.Testicular sections with PAS staining showed cell cycle arrest of the sperm from Agtpbp1-/-mice.CONCLU-SION:In this study,Agtpbp1 knockout mice were successfully bred.The deletion of Agtpbp1 caused the arrest of sper-matogenic cell differentiation and the decrease in sperm motility in adult male mice,resulting in infertility.At the same time,it provides a new experimental tool for further exploring the molecular mechanism of Agtpbp1-induced male sterility.

Objective:To analyze the regional differences in health resource allocation in Guangdong Province and provide references for optimizing health resource allocation in Guangdong Province. Methods:The health resource density index,entropy weight-TOPSIS method,and RSR method were used to comprehensively evaluate the allocation of health resources in Guangdong Province from 2018 to 2022. Results:The results of the entropy weight-TOPSIS analysis showed that the average levels of comprehensive evaluation in the Pearl River Delta,Western Wing (West Guangdong),Eastern Wing (East Guangdong),and mountainous areas (North Guangdong) from 2018 to 2022 were 0.4452,0.1338,0.2144 and 0.0566,respectively. The RSR grading results show that Zhuhai,Dongguan,Guangzhou and Shenzhen had better allocation of health resources,with a"good"grading result;Shaoguan,Yunfu and Heyuan are worse. Conclusion:There is an obvious regional difference in the allocation of health resources in Guangdong Province. The allocation level of health resources in the Pearl River Delta and the Eastern Wing (East Guangdong) is relatively high,while the allocation level of health resources in the western wing (West Guangdong) and the mountainous areas (North Guangdong) is relatively low. In the future,Guangdong Province should pay attention to the areas with poor allocation of health resources,develop regional characteristic economy,strengthen the training of health talents,optimize the allocation of health resources,and realize that all people in the province can enjoy high-quality,convenient and equal medical and health services. At the same time,it is also necessary to strengthen cooperation and exchanges among regions to jointly promote the comprehensive development of health undertakings in Guangdong Province.

Objective: To understand the attitudes and perceptions of traditional Chinese medicine (TCM) practitioners in Beijing TCM hospitals regarding the use of Ephedra sinica Stapf (E. sinica, Ma Huang). Methods: A two-stage cross-sectional study was conducted using a questionnaire survey of TCM practitioners in Beijing TCM hospitals between April 2023 and March 2024. The questionnaire included demographic information, the clinical background of TCM practitioners, and the clinical application of E. sinica. Logistic regression analysis was used to analyze the relevant influencing factors when using E. sinica. Results: Of the 465 questionnaires collected, 441 were valid. Among these, 84.81% (374/441) reported having used E. sinica in clinical practice at least once. The commonly used doses of E. sinica—excluding the pediatric department—were 10 g for high doses, 6 g for medium, and 3 g for low. The three most frequently used formulas for E. sinica included Maxing Shigan decoction, Mahuang decoction, and Xiao Qing Long decoction. The most common TCM patterns treated with a high dose of E. sinica were wind-cold exterior pattern, wind-cold invading the lung, and wind and water combat with meridians congealed by cold. The top three Western medical diagnoses when using E. sinica for treatment were common cold, pneumonia, and upper respiratory tract infections. Nearly half of the respondents reported experiencing adverse reactions from the oral administration of E. sinica, with the most common being palpitations, insomnia, and restlessness. Starting with a low dose and gradually increasing it as appropriate was identified as an effective approach. Conclusion This study investigated the attitudes and perceptions of TCM practitioners in Beijing TCM hospitals regarding the dose–efficacy–adverse reaction relationship of E. sinica, providing a reference for the safe and effective clinical use of E. sinica.
